I hate to see a pal in distress about an 'elektic' device so here is how to lock, or indeed unlock, a device settings before switching off to prevent you having to go through the same re-setting each time you switch back on. The Neostar Onizuko Scanner is a case in point.
I have always had success by using this trick and I hope it works for you:
Simply hold down the one or two buttons in question, but hold them down while switching the Scanner or device off! Works every time for me.
